The Gamo "Bone Collector" slingshots are simply re-branded Man Kung slingshots - two of them are copycats of Daisy slingshots.

The normal "Elite" is simply the Man Kung Sl-08, which is basically a Daisy
P51 with a new handle and a pretty weird sight that points inside the fork. I cannot see how this
sight is supposed to help aiming.
An upgraded Elite version exists. It has a flashlight and a
fixed laser sight on the front. Now a non-adjustable laser sight that is fixed to the
frame will point anywhere, but certainly not to your point of impact. It still has the
weird inside-fork sight, so this slingshot
it equipped with two sights that are useless to the shooter! The "upgraded"
Elite also has a plastic pouch with a petal-shaped part that is meant to hold the
ammo centered.
